EXPLOSIVE-ENGINE.

Specification of Letters Patent.

Patented Oct. 29, 1912.

Application filed December 6, 1911. Serial No. 664,256.

'o all whom it may concern:

lle it known that I, HARRY lV. Moons, a citizen of the United States, residing at Nebraska City, inthe county of Otoe and State ot' Nebraska. have invented a new and useful Ex;ilosive-lhigine, ol" lwhich the tollmving is a specilication.

The present invention relates to improvements in explosive engines, this particular Aconstruction being an improvement upon apf said sleeve providing a l. better connect-ion and at the same time assisting as a carbureting medium, in that the heat therefrom. when projected beyond the ends ot the cylinder will assist in the rapid carburation and expansion of the gas and air while it Vitseltl will be cooled by the inrush of the earburetcd air.

il. further object ot' the present invention is the provision of a cylindrical sleeve for comliecting the respective pistons tor movement in unison. said sleeve being composed of a `material having the same coellicient ot expansion as the easingand pistons so thatthe lit` therebetween' will be proper at all times, the said sleeve also acting as a sliding valve to-control the intake and exhaust' of the explosive mixture from the respective explosive chambers of the engine.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the conn bination and arrangement of parts and in the details ot construction hereinafter described and claimed, it heilig understoml that changes in the precise embodiment ol' invention herein disclosed can be made within the scope of what is claimed without departing trom the spirit of the invention.

ln the drawings-Figure .l is a side elevation taken from the intake side of two cylinders ot' an engine embmlying the present invention. Fig. 2 is a vertical longilndinal sectional view theretlnougli. Fig. S is a. cross section taken through the exhaust ports ofthe main cylinder' of one enit, with the pistons in their highest positions. Fig. 4. is a section taken on line t-lt or' Fig. Fig. 5 is a section taken on line ot Fig. 3. Fig. 6 is a perspective view ot' the connecting sleeve for the two 'piston heads. Fig. T is a top plan view of one ot the piston heads.

Referring to the drawings, it will be noted that the exterior construction of the present engine is identical with the structure ot the engine set forth in the atorelnentioned application, and that the greater portion thereof is identical.

In the present instance, the numeral l vcylinder volf the engine is a unit. as in the aforementioned application.

Each cylinder is provided with the peculiarly shaped centrally disposed water jacket 4, and mounted cent 'ally wit-hin the main cylinder' C is a. main explosive cylinder 5, which is divided cent ally by means ot' the diaphragnror partition .into the oppositely disposed explosive chambers 7 and S respectively. 'lhis partition or diaphragm (il is provided with the depress-ed portions (3 which are in line with the spark plug apertures S) t'or the spark plug `l0. In order to properly retain the spark plug and at the same time hold the explosive cylinder 5 in its proper relative position to the outer cylinder Q of the engine and provide a concentric space therebetween, the two couplings 13 are employed, the same being secured through the diametrically disposed apertures yof the main cylinder 2 and being` threaded into the apertures 9 of the cylinder 5. Hy this means the respective explosive chambers may be sinriplied with the proper spark, and the plug may be removed Jfor cleaning when' necessary. ,i 1

Mounted for sliding movement in the con centric space between the cylinder and the inner wall of the main cylinder 2 is a cylindrical sleeve 11 provided with the diametrically disposed elongated slots 12 which are mounted to slide upon the respective couplings 13, the said elongated slots 12 being so positioned and of such a length as to permit of t-he proper reciprocatory movement of the sleeve 11'.

Provided in the upper and lower portions, respectively, of the main cylinder 2 are carbureted air intake ports 14 and 14 and leading from the respective chambers into which the said carbureted air is drawn, are

the vertically disposed conduits 15' and 18Y respectively, the conduit 15 being the sup ply conduit for the upper explosive chamber 7 and terminating in the intake port 16 atthe upper end thereof, as clearly shown in Figs. 2 and 3. The other conduit 18 leads into the upper end of the main cylinder 2 and secures its explosive mixture throu h the intake 14 to be delivered through tie jjntake port 18 to the lower explosivecham- Both of the respective explosive chambers 7 and 8 are provided with exhaust ports 17 and 19r respectively and are in line with the respective exhaust ports 20 and 20 the same remaining in the same relative position at all times.

The sleeve 11 is provided upon its lower end with the grooved inwardly projecting annular portion 21 for the reception of the locking ring 22 which is adapted to tit within the grooved portion thereof and upon the lower end of the piston 23, the envlarged piston 25 being connected tothe lower end of the piston 23 by means of the bolts 24 which lockthe lower end 21 of the sleeve 11 thereto so that the piston 23 and piston 25 will be properly connected together, the piston 25 itting the carbureted air compression chamber 26 at. the lower end for supplying the carbureted air through the passage 15 to the intakes 16 4and 16 of the main cylinder 2 and the explosive chamber. 7.`

The upper end 27 of the sleeve 11 is formed in the same manner and carries the piston head 28 andthe enlarged piston, disk 29 for supplying the carbureted air from the compression chamber 30 through the vertical conduit 18 to the intake 18 of the lower explosive chamber 8. By this means it will be seen that the two piston heads 23 and 28 will reciprocate in unison in a like manner to those shown in the'aforement-ioned application, the lower piston head 23 being connected directlyV by means of the piston rod 31 to the crankshaft C so that" the proper.

rotary motion may be imparted thereto.

As clearly shown in Fig. 31the pistons 23 and 28 are formed with a peculiar shaped baille 32, the same instead of being a plate secured to the top thereof being an enlarged portion providing the under depression 33 in communication with the lower hollow portion of the piston so that the upper surface of said piston may be properly cooled and not permitted to be supersheated during the explosion, and operation of the engine. This projection also tits within its respective chamber G formed in the diaphragm G and permits the maximum stroke within the minimum space.

From the foregoing description taken in connection with the drawings, it is evident that the lower and upper ends of the sleeve ll-which projects into the respective chainbers 26 and 30 and due to the heat from the explosive charge will provide an increased carbureting surface in that thefcharge of the earbureted air being taken into the respec- 4 tive intakes 111 or 1t will beprojected suddenly upon thewarin cylindrical surface cncircling the same, thus being rapidly heated and consequently expanded so that when the piston moves in the opposite direction the explosive charge will be propelled in a thoroughly mixed and heated condition into the respective intake ports of the casingor cylinder 5 so that a proper heated and expanded carbureted air will be the resultant. By this means it is also evident that the explo sive chambers 7 and 8 will be properly scavenged sothat the burnt gases will be properly expelled from the respective chambers and the desired explosive mixture will be retained therein at the highest point of compression to be'exploded. lt is also evident by providing a sleeNe such as 1l for connecting the respective pistons together that the projection of the carburetcd air thereagainst will act as a cooling medium and will assist in cooling the saine, and further by reason of the fact that the metal of the sleeve 11 is the same as the metal of the cylinder 5 and outer casing`2, such mytal havingthe same co-etlicicnt of expansion as the respective surrounding metal, that the liability to bind' is lessened. lt is also evident that by reason of the ports it and 3l. and 35 and 35 formed in the walls of the cylindrical connector and sleeveI l1 and adapted to register with the respective intake and exhaust ports 16, 16217, 19, 20 and 20, that the opening and closing thereof will be regulated entirely by the movement, ol' the respective pistons so that the intake otlhc carbureted air and the exhaust oi' the burnt `iras will bc properly timed and will be controlled entirely by means of the said con,-

V necting sleeve 11.

By dispensing with the connecting rods as y shown in the above mentioned application and employing in lien thereof the sleeve 11 with the respective diamctrically disposed slots 12, the assembling of the present strncture is more easily accomplished and itl is not so liable to prevent they; proper alinement of the various ports "amd by lift lli

reason of the peculiar connection bctween` the piston heads and the lower and upper ends ot said sleeve l1, a proper and rigid connection is provided and one which Will not leak at any point as it is conl:nected tightly throughout the entire ends however, that the sleeve ll has over the respective rods in the former case, is that the same provides a better and rigid connection between the pistons and atthe same time reduces the size oi' the respective chambers 26 and 3U and causes the inrush of cool vcarlbureted air to be circulated about the entire surface oil the extended end of the sleeve .11 within the respective chambers so that each o the said projected ends of the sleeve 11 'will produce a rapid means for increasing the Carburation and expansion of the gas to produce better explosive mixture. yThe other result ot this is the cooling of the respective projected ends of the sleeve ll by the inrush of the carbureted air through the respective ports 14- or let.
